permit a certain amount'of yielding on the part' of the ring underoperating conditions and at the same time act as a dampener to reducevibration and noise. A further object is to provide 6 Claims. (01.51-122) reception of each such ring 2 the rail is formed with a circularopening 4 of somewhat larger Gil a mounting which will permit of theready placement of a ring in the supporting member without requiring theuse of any tool, while at the same time a firm and secure mounting isprovided for said ring under operative conditions.

To the accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully describd and particularlypointed out in the claims;

The annexed drawing and the following de scription set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which the,principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a plan view of a typical spinning ring shown as supported byour present improved mounting in a ring rail; I

Fig. 2 is a transverse section of the foregoing, the plane of thesection being indicated by the line 22, Fig. 1; V

Fig. 3 is a sectional view on a larger scale of ring and the mountingtherefor; and.

Fig. 4 is a sectional view similar to Fig. 3 but showing a modificationin construction.

The ring rail i, as shown in Figs. 1 and 2, is

of usual construction, consisting of a channelform member. pressed fromsheet metal and of diameter than the exterior diameter of the ring bodyalthough the latter may have a radially projecting flange I of the sameor slightly larger diameter than such opening. In addition, the body ofsaid ring is formed with an encircling groove 6 located in spacedrelation below suc For the purpose of mounting the ring in the openingin the ring rail a grommet or gasket 1 of special cross-sectional form,as will now be described, is provided, such grommet being composed ofresilient material, e. g. ofrubber, either natural or synthetic,vulcanized to the desired degree, or of equivalent resilient,compressible,

material. This grommet is interposed between the outer face of the ringbody and the edge of the opening l in the ring rail and constitutes thesole connecting means between the two parts in question. As best shownin Fig. 3, said grommet is formed with an inwardly directed rib 8 thatis adapted to seat in the recess 6 in the ring body and with aperipheral groove 9 that is adapted to engage the. edge of the opening 4in the ring rail. While such groove is formed so as to em brace suchedge more or less closely, the rib l I on the grommet in theconstruction under con-;

sideration is of less depth, or cross-sectional area, than recess-i. Thelatter, it will be noted, is

placed andthe corresponding edge of the recess in the grommet may beslightly rounded as shown in Fig. 3.

ways 3 whereon the spinning or twisting device (not illustrated) isrotatably supported. For the In the assembled condition of the parts therib or flange I on the body of the ring rests on the upper face of thegrommet and such ring is additionally held in place relative to thegrommet by the'engagement between recess 6 therein with the inwardlydirected rib I on the grommet.

' Finally, the latter is secured in place by engage-- ment of theperipheral groove in its'outer face with the edge. of the opening in thering rail; However, due to the resilient, compressible, characterof saidgrommet, upon forceful movement of'the ring in a downward directionaxially of such opening a portion of the grommet adjacent rib l'tliereonwill be squeezed into the space normally remaining between such' rib andthe bottom of groove tin the ring. This space will be 'sufllcient'toaccommodate the volume of such displaced material and the. latter willbe'sufflcient to permit the grommet to slide past the radially outwardlysufilciently to disengage it from the ring, if desired.

In the modified construction illustrated in Fig.

4 the ring rail i and ring 2 are of substantially the same constructionas that described above,

the only difference being that the peripheral groove iii in the body oithe ring is curved at its bottom instead of being of rectangularcross-sec in such an opening. Thus said ring, and the opening wherein itis mounted, may be of other than circular form and be designed for otheruse than to support a spinning or twisting device.

tion. Likewise, the grommet ii is of substantially the same constructionas gasket 1 except that the rib l2 thereon, which is designed to engagesuch groove I0, is of substantially the same conformation so as tocompletely fill the latter. -'Also the outer face of the grommet inwhich is formed a groove I! designed to engage the edge of the opening 4in the ring rail more closely engages both sides of the latter adiacentsuch opening than in the case of grommet I. Finally, said grommet isiormed on its inner face immediately below rib I! with an inwardlydirected encircling groove M.

In the assembled condition of the parts the grommet ii obviously willfunction in identically the same way as grommet I to support the ring 1in the opening in the ring rail. when it is desired to remove the ring,pressure is' applied thereto as before. and the portion oI the grommetadjacent such last-mentioned groove ll will be compressed and displacedto a suiiicient extent to permit the groove 13 in such grommet to be disengaged from the edge of opening 4 in the ring rail. and displacement ofsuch portion of the grommet the latter may be forced downwardly throughsuch opening until the groove in question is again ..rought intoengagement with such edge.

It will be understood that in the operation both of removing and thusinserting the ring in place in its mounting the grommet will remainattached thereto by engagement of rib II on the grommet with groove iiiin the ring. It will also be noted that the lower outer face of saidgrommet is beveled or inclined outwardly, which serves to facilitateplacement oi the ring, with the grommet carried thereby, in the openingin the supporting member. u

As previously stated, in both of the two illustrative forms of ourimproved spinning ring mounting the grommet constitutes the soleconnecting means between the ring rail or equivalent supporting member,i. e. there is nowhere any metal-to-metal contact between the parts inquestion. At the sametime. owing to the unique form and construction ofthe grommet. removal and replacement of the ring may be readilyaccompllshed without detracting from the security with which it is heldin place in the assembled condition of parts.

A} likewise previously remarked, the ring rail i is merely illustrativeof a similar supporting member, in an opening in which it is desired tomount a ring. Similarly the term "ring" as used herein is to beunderstood as eonnoting any equiv- Conversely. by correspondingcompression Finally, it should be noted that depending on therelativeextent axiallyof the (edge of the opening in the supporting member" andof the juxtaposed outer face of the ring the disposition of grooves andribs on the grommetmay be reversed.

- Other modes of applying the principle of our invention may be employedinstead oi the one explained. change being made as regards the mechanismherein disclosed, provided the means stated by'any, of 'thefollowingclaims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as ourinvention;
